[pkg-cryptsetup-devel] Bug#648868: cryptsetup: Please add support for allow-discards option in crypttab

[Peter Colberg]

Dear Maintainer,

I extended the patch for TRIM support in crypttab to include the
cryptroot initramfs script. Further the option “allow-discards” is
renamed to “discard”, which avoids a hyphen in the parameter name:

PARAM=allow-discards
VALUE=yes
eval export CRYPTTAB_OPTION_$PARAM="\"$VALUE\""
/bin/dash: 1: export: CRYPTTAB_OPTION_allow-discards: bad variable name

Besides avoiding a hyphen, this follows the style of crypttab options,
e.g. --key-size → size. e2fsprogs names the option “discard” as well.

Regards,
Peter
